Abstract

L'invention concerne un dispositif transversal à aubes permettant d'éliminer autant que possible la courbure d'une zone de manipulation de fil au point de retour d'un chemin transversal, assurant le transfert d'un fil entre une aube transversale supérieure et une inférieure, et comprenant un guide transversal (4) pourvu d'une surface de guidage (10) constituant un chemin transversal du fil, qui mène à un rouleau de contact (3). Ce dispositif comprend également deux niveaux d'aubes transversales (5, 6) servant à transférer un fil aux points de retour droit et gauche (a, b) situés sur la surface de guidage (10) et tournant dans des directions opposées l'une à l'autre lorsqu'elles rentrent et sortent de la surface de guidage (10), de telle manière que le fil peut être livré vers la droite ou vers la gauche, le long de ladite surface (10). Les guides (8, 9) du fil permettent de stabiliser la zone de manipulation allant de la surface de guidage (10) au rouleau de contact (3), à proximité des points de retour (a, b).
